Abstract：
BACKGROUND: There were controversial findings in terms of the association between the incidence of Benign Paroxysmal Positional Vertigo (BPPV) and climate changes, so the current systematic review plus meta-analysis is designed to discover this possible relationship.
METHODS: Web of science, PubMed, Scopus, Google Scholar, Embase, and Cochrane library were systematically searched up to August 2023. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Problem/Population, Intervention, Comparison, and Outcome (PICO) guidelines were used. Two authors independently reviewed the eligible articles and assessed the quality of them.
RESULTS: In total, 15 studies including 16144 patients met the inclusion criteria. Ten studies reported the relation of BPPV to monthly mean temperature, 7 to monthly average humidity, 4 to monthly average rainfall, 6 to monthly sunlight time, and 2 to average solar radiation. The incidence of BPPV was associated significantly with atmospheric pressure (P: 0.003) and rainfall (P: 0.017). However, there was not any statistically significant correlation between incidence of BPPV and humidity, sunlight time, temperature, and solar radiation level (P > 0.05).
CONCLUSIONS: The incidence of BPPV was higher in cold months of a year in both northern hemisphere and southern hemisphere countries. Although it can be because of negative correlation with temperature, the current meta-analysis did not find any statistically significant negative correlation with temperature. In addition, the incidence of BPPV was associated significantly with atmospheric pressure (positive correlation) and rainfall (negative correlation).

摘要：
背景：在良性阵发性位置性眩晕（BPPV）的发生率与气候变化之间的关联方面，有争议的发现，因此，目前的系统评价和荟萃分析旨在发现这种可能的关系。
方法：Webofscience，PubMed,Scopus,谷歌学者，Embase,和Cochrane图书馆进行了系统搜索，直到2023年8月。系统评价和荟萃分析(PRISMA)和问题/人口的首选报告项目，干预,比较,并使用结果（PICO）指南。两位作者独立审查了合格的文章并评估了它们的质量。
结果：总计，包括16144名患者在内的15项研究符合纳入标准。十项研究报告了BPPV与月平均温度的关系，7至月平均湿度，4至月平均降雨量，6至每月日照时间，和2平均太阳辐射。BPPV的发生率与大气压力（P：0.003）和降雨（P：0.017）显着相关。然而,BPPV的发生率与湿度之间没有任何统计学上的显着相关性，阳光的时间，温度,和太阳辐射水平(P>0.05)。
结论：在北半球和南半球国家，一年中寒冷月份的BPPV发病率较高。虽然这可能是因为与温度呈负相关，目前的荟萃分析未发现与温度有统计学意义的负相关.此外,BPPV的发生率与大气压（正相关）和降雨（负相关）显着相关。
